What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Converting 108kg to UK Measurements
To convert 108kg to stone: divide 108 by 6.35029. This gives you 17 stone and 0.2 pounds. To break this down further: 108kg = 17 stone (which equals 238 pounds exactly). Using the standard kg to stone conversion formula, 108kg falls firmly in the upper weight range for UK adults.
For reference, the average UK adult male weighs around 85.7kg (13st 7lbs) and the average UK adult female weighs around 71.6kg (11st 3lbs), according to ONS data. At 108kg, you are significantly above these averages, which has implications for your health.

What Does 108kg Mean for Your Health?
At 108kg, your health context depends on your height. For example, an adult male of average height (5ft 9in / 175cm) would have a BMI of approximately 35.3, which falls into the obese (Class II) range according to NHS guidelines. This BMI category is associated with increased risk of type 2 diabetes, cardiovascular disease, and other weight-related health conditions.
The good news: even modest weight loss of 5–10% of body weight can lead to meaningful health improvements, including better blood pressure control, improved blood sugar levels, and reduced joint strain. Your GP can assess your individual health picture and discuss weight management options with you, which may include lifestyle changes, support programmes, or prescription medications if clinically appropriate.
